. The application note interconnection requirements take
precedence over the requirements stated in this manual.
Neutral Requirements
The physical neutral conductor from the inverter to the point of interconnection is optional, but not recommended.
It is used by the inverter for voltage sensing only and does not carry current. Therefore, the neutral conductor size
may be reduced to a size no smaller than the EGC. These inverters have their ground and neutral terminals bonded
internally.
NOTICE!
Neutral to Ground Jumper:
Do not use a jumper between neutral and ground in the inverter wire box if the
neutral conductor is already connected ground at the point of interconnection (electrical panel or transformer).
Using a jumper with the neutral conductor connected may result in damage and void the warranty.
Electrical Installation AC, Method
DANGER
Electric Shock Hazard:
Components with hazardous voltage and energy will electrocute operator. Operator shall
avoid touching live components with hazardous voltage and energy. Verify the absence of voltage using an
appropriately rated multimeter.
Always Wear Proper PPE:
The proper Personal Protective Equipment (PPE) must be worn while working in
proximity to hazardous voltage and energy.
Conduit Installation:
All conduit connections must be made in such a way as to maintain the NEMA 4X rating of
the enclosure. Failure to maintain the NEMA rating will void the warranty.
This section includes instructions to connect the AC conductors to the inverter and grounding options.
